Add beets, carrots and onion to a medium saucepan, cover with water and bring to a boil. Cook for 10-15 minutes or until tender.
While vegetables are boiling, add remaining ingredients (2/3 cup water through spices) to blender (high speed like a Vitamix is recommended for silky smooth texture). Strain and add vegetables to blender when they are through cooking.
Carefully blend on high until liquefied.
Return blended mixture to sauce pan and bring to a boil. Reduce heat to low and simmer for 30 minutes until desired consistency is achieved.
